We can't start scheduling task with turn off device. This would be great if you need to restart devices like modems for eldery and such.

Another great feature would be a 'reset button' which would turn off smart plug for 10 - 30 seconds and then turn it back on without other user input.

More elaborate I wrote to Customer support:

I would like to get a software improvement. In scheduling for the kasa smart plug, you can't schedule them to turn off and then turn on. You can only start scheduling with turn on step. I want to be able to start scheduling with turn off then turn on. Another great thing would be if we had button which turns off the plug for lets say 10 seconds and then turns it back on; that way you can restart routers from outside of the house.
